LM2738XMYEVAL boards are used to facilitate the evaluation of power converters and are classified as evaluation boards for DC/DC & AC/DC (Off-Line) SMPS. The boards are based on the LM2738S IC, a single step-up converter power supply controller which features a total power of 27V/380W, current mode control and a current limitation of 5A.

The LM2738XMYEVAL includes the LM2738S IC which can be used to evaluate the IC itself or as an evaluation platform for customized DC/DC & AC/DC converters.

The LM2738XMYEVAL boards take an input voltage range of between 3.4 volts and 17V and has programmable output voltage up to 28V with a peak current of 5A and a peak power of 380W. The board supports either the constant frequency current mode control and the optional skip mode feature. The board also features current and temperature monitoring with an onboard temperature sensor.

The current mode control allows the LM2738XMYEVAL to provide higher peak currents and also allows for smoother output load and line fluctuations. It also features protection against overload, short circuit and under voltage conditions. The onboard temperature sensor allows the board to monitor the temperature of the IC and provides thermal protection of the IC.

The board supports external synchronization of the internal clock and a variety of external control signals such as those used for dimming and other applications. The board also has a reference voltage output which can be used for other external applications.

The LM2738XMYEVAL board also supports digital communication, allowing the user to program and configure the device remotely via the UART interface. This allows the board to be controlled through a variety of communication protocols such as RS485 and I2C.

In conclusion, the LM2738XMYEVAL board is an evaluation board for DC/DC & AC/DC (Off-Line) SMPS which allows developers to evaluate the capabilities of the LM2738S IC. It features a wide input voltage range, programmable output voltage, current and temperature monitoring, protection against overload and short circuit conditions and support for external synchronization and control signals. The board is also compatible with digital communication for remote programming and configuration.
